The Scholar of Destruction usually represents knowledge of an unfortunate event in the future and actively working to prevent this from happening, learning from past mistakes, or selflessness and benevolence.

Reversed it can represent hardwork, logic and great enthusiasm for something which will ultimately lead to disaster.This could be through naivety or even knowingly, but in either case can have serious repercussions. It can also represent self-destructive tendencies or behaviour, obsessiveness, or even megalomania (in an evil-genius kind of way)
